Building quiet systems for distant ideas.

Full-stack software engineer based in Tokyo with 3+ years building, maintaining, and operating production web systems — with a strong backend focus. Started in C#/.NET backends in Italy, crossed over to Japan via a year of language training, and now works across Ruby on Rails, Go, and Java/Spring services on Japanese-speaking Agile teams.

Currently at a fintech startup in the digital ID, payment, and transaction-services domain. I like software that turns messy operational work into calm, inspectable flows: clear data boundaries, reliable APIs and batch jobs, and small details that make repeated use easier instead of louder.
